From my observations it appears that the majority, if not all 4 fin 61 cubic inch cylinders had the raised shield. 5 fin 61 cubic inch had MC stamped or possibly cast on them, and 74 cubic inch cylinders had the raised shield.
I would be interested to see if anybody has cylinders with stampings that are different ?
